3.) Most people assume that vision is what your eye sees and reports to your brain. Actually, the brain adds a great deal to the report it gets from the eye; much of what you see is “made up” by the brain.

4.) A baby’s brain triples its size in the first year of life.

5.) Men’s brains are on average about 9% bigger than women’s brains. (This does not mean men are smarter than women!)
